' 2 Claims. (Cl. 29-261") This invention relates. to a novel'tool or implement which is especially adapted for several types of machines using. sleeve governors, thesame-being particularly useful in dislodging and then removing thesleeve, but being adaptabletoaccommodate. other typesand kinds of bushings and sleeve-like elements.

It has beenthe practice in the past to remove shafts from dynamos: and. water pumps and then put the. same. same in avisev andpound the sleeve off with a hammer and a chisel, or any other device or tool at. hand. This takes considerable time, obviously. And, too, governor sleeves stick. and

are extremely difficult-to remove. The purpose of the present invention isto provide a novel structural tool or implement which. is especially applicable to remove sleeve governors, anditis my aim, .incarrying out the principles of the invention, to provide a structure which is comparatively simple, economical, easy to handle, and which is reliable in achieving the desired aim.

The preferred embodiment of the invention is characterized by a sturdy frame structure in the form of an adapter yoke, there being slidably and adjustably mounted thereon a double jaw unit so constructed and coordinated with the other parts as to provide an over-all structural adaptation which lends itself admirably well to accomplishing the results desired,

Other structural features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevational view of a sleeve dislodging and removing tool or device constructed in accordance with the principles of the present inventive conception.

Figure 2 is a top plan view of the structural arrangement seen in Figure 1.

Figure 3 is an end elevation of the structure appearing in Figures 1 and 2.

Figure 4 is a fragmentary detail elevational view through the central or hub portion of the structural assemblage as a whole. I

Figure 5 is a top plan view of the arrangement of parts depicted in Figure 4. I

Figure 6 is a section on the line 6-6 of Figure ,1 looking downwardly in the direction of the arrows.

Referring now to the drawings by distinguishing reference numerals, it will be observed that an obvious manner.

characterizedby two major units or parts; namely,.thefoundationor frame structure A and the dual adjustable, slidable' sleeve-gripping unit'B.

The frame is made up of a pair of spaced, paral 1e1 longitudinal frame bars 1. I provide three assembling. and: spacing blocks; twoouter duplicate. blocks 8 and. 9 secured. between the frame bars byrivets Ill. Theseblocks 8 and 9 have their outer ends spaced inwardly from the corresponding outer ends of. the framebars and. their inner ends spaced from the central adapter blockl I also held in: placeby rivets l2. Thiscentral block H is provided witlr a seating notch 13 and. the frame bars: on. oppositesides thereof are provided with aligned suplemental notches I341. The limbs or arms of the frame unit are denoted bythe numeral M. Theseare disposed atthe opposite ends of the frame structure andv have their upper or inner ends bolted, asat Ma, between the frame bars andagainstther adjacent ends of the: spacing blocks 8 and; 9. The spacing blocks are provided with; integral upstanding lugs: I5 having. screw threaded holes, said lugs functioning as nuts for the threaded ends N5 of the bolts H. The outer ends of the bolts are provided with wing nuts l8 and the adjacent end portions are rotatable in the companion lugs l9 formed integral on the upper ends of the limbs M. The lower free ends of the limbs are provided with detents or retaining pins 20. So much for the frame and other parts associated directly therewith.

Coming now to the specific construction of the jaw unit B, it will be observed that this comprises a pair of elongated jaw members 2| disposed in parallelism and having their lower ends suitably tapered and shaped to provide gripping elements 22 for the sleeve 23 (see Fig. 6) in These jaw members Zlpass upwardly through the guide openings formed between the central block II and the adjacent inner ends of the complmental spacing blocks 8 and 9. The protruding upper ends are provided with bolt holes 24 toselectively accommodate bolts 25 passing through the furcations or ears 26 provided at the outer ends of the crosshead 21. central body portion 28 is screw threaded to accommodate the set screw 29. The adjusting and retaining bolts I! atop the frame structure have their inner ends engageable with the adjacent intermediate portions of the jaw members 2|. The set screw has its lower end pointed and engageable in the seats or notches I 3 and Na. Thus, the bolts 25 can be loosened and tightened tomake for adjustment of the jaw-equipped memthe preferred embodiment of the invention is 55 bers 2| by way of thebolts ll. Then, the set The' unit B at right angles to the frame structure A in an obvious manner to dislodge and remove the sleeve, collar or part 23 from its shaft (not shown).

The aligning and adjusting wing-head bolts I! are loosely turnable in the guide and assembling lugs l9 and the inner threaded ends are fed through the nut-like lugs [5 to engage the parts 2|, sometimes referred to as straddle bars. In-I cidentally, these straddle bars arev reversible. That is to say, they can be removed from the retaining ears 26 by detaching the bolts 25. This permits the jaw ends or elements 22 to be turned outwardly. instead of inwardly toward each other, as shown in Figure 1 of the drawings.

Although'the invention is shown and described as especially adaptable for removing collars and sleeves such as are used in different types of machines employing sleeve governors, it is evident that the constructionis such as to permit the parts to be rearranged and adapted for handling bushings, thimbles and the like in other types of machinery. t

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sumcient to clarify the construction of the invention as hereinafter claimed. 7 1

Minor changes in shape, size, materials and re;-

arrangements of parts may be resorted to in' actual practice solong as no departure is made from. the invention as claimed. 3

I claim:

,1. 'In a governor sleeve dislodging and removing tool, a frame'structure comprising a pair of longitudinally extending, parallel frame bars, an intermediate block fastened between the intermediate portions of said frame bars, a pair of end blocks fastened between the end portions of screw 29 can be used to bodily shift the entire said frame bars and having their inner ends spaced from the intermediate block to provide guide openings, and having their outer ends spaced inwardly from the outer ends of the frame bars, and a pair of limbs having their upper ends bolted between the outer ends of the frame bars andabutting the outer end portions of the outer spacing blocks, the lower ends of said limbs being reduced to provide detents, inner and outer lugs rising in spaced pairs from the top portion of said frame structure, the respective inner lugs being provided with screw-threaded bolt holes and the outer lugs having openings to accommodate and provide bearings for bolts, and bolts passing through the hearings in said outer lugs and having their inner ends screw-threaded and threaded into the bolt holes in said inner lugs. 2. In a governor sleeve dislodging and removing tool, a frame structure comprising a pair of longitudinally extending, parallel frame bars, an intermediate block fastened between the intermediate portions of said frame bars, a pair of end blocks fastened between the end portions of said frame "bars and having their inner ends vspaced from the intermediate block to provide guide openings, and having their outer ends spaced inwardly from the outer ends of the frame bars, and a pair of limbs having their upper ends bolted between the outer ends of the frame bars and abutting the outer end portions of the outer spacing blocks, the lower ends of said limbs being reduced to provide 'detents, and a bodily ad- .iustable double-jaw unit including a crosshead having a central screw threaded body portion and bifucated ends, the furcations constituting assem-' bling ears, a set-screw passing through the screw threaded body portion, a pair of jaw-equipped members, the upper ends'thereof being bolted detachably between said ears and the jawequipped ends being slidable' through said guide openings.
